TRASH- DRILL.

BPECIFICA'I'ION forming part of Letters Patent No. 346,234, dated July 27, 1886.

Application filed May '20, 1886.

To all whom it may concern.-

Be it known that 1, Burns ARTHUR SUM- MERS, a citizen of the United States, residing at Mount Vernon, in the county of Jefferson and State of Illinois, haveinvented certain new and useful Improvements in Trash-Drills, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in seedingmachines; and it consists in the construction, combination, and arrangement of the several parts, as will be hereinafter more fully described and claimed.

In the drawings, Figure 1 is a side view, part in section, of a machine constructed according to my invention. Fig. 2 is a rear elevation of the revolving shovel. Fig. 3 is a vertical section thereof on about lineXX, Fig. 5. Fig. 4is a vertical section of the middle portion of the shovel on about lineYY, Fig. 2. Fig. 5 is a detail side view of the shovel and connecting-tube. Fig. 6is aperspective view of the shovel and connecting-tube. Fig. 7 is a front view of the connecting-tube. Figs. 8 and 9 show modifications, all of which will be described. Fig. 10 is a side view of a modified form of machine. Fig. 11 is a plan View of the same. Fig. 12 is a vertical central sectional view of the shovel, showing the hub in place. Fig. 13 is an enlarged detail perspective view of the mechanism for forcing apart the draw-bars and drawing them together. Fig. leis an enlarged detail perspective view, part broken away, of the cap for closing one side of the shovel and forming a hub therefor; and Fig. 15 is an enlarged perspective view of the delivery-spout. Fig. 16 is a detail crosssection taken in front of the stops.

I have shown the supporting or main frame of the machine as composed of top bar or platform, A, provided with bracket A, in which is journaled the wheel B. It will be appreciated, however, that the framing may be modified or altered without departing from the principles of my invention, which will be hereinafter disclosed.

On the platform A, I mount the seed-box 0, provided with a suitable discharge-opening, below which projects the spout O, which connects with and extends into a sleeve, D, depending from the platform. The upper end of the spout may be pivoted, if desired, as

Serial No. 202,791. (No model.)

shown in Fig. l, or it may have a fixed connection, as shown in Fig. 10. In the latter case the sleeve is dispensed with. The beam E is suitably supported at its forward end on the main frame, and its rear end is bifurcated by slot E, forming the arms E; or it may be made of two plates E secured together, leaving sufficient space between them for the flukes or shovels to pass through. Aspring, F, may be arranged at the inner end ofthe slot E, or between the plates or arms E, in such position to be engaged by the points of the flukes or arms of the revolving shovel, presently described.

Instead of the spring F, stops F may be secured on the inner sides of the plates opposite to each other. By these means the shovel is normally held from revolving. A bolt, M, passing transversely through coincident openings in the plates E,has springs m inserted between its head and the nut and the sides of the plates, respectively, for normally keeping the plates together and preventing their spreading,except under the conditions hereinafter set forth. It is desirable that the springs F and n have sufficient tensionthe one upward, the other laterallyto hold the arm engaging with the spring or stops, respectively, and prevent the revolution of the shovel so long as normal or ordinary pressure or force is exerted against the fluke operating the ground, and at the same time permit the partial revolution of the shovel when the fluke in the ground strikes a stone, stump, or other obstruction or accumulates a quantity of trash, as will be readily understood.

The shovel G is composed of hollow arms or flukes G, preferably four in number, and ar ranged as shown, the adjacent ones being at right angles to each other. These flukes are hollow their full length, and the openings in the opposite flukes meet at the center, thereby forming tubular passages crossing each other at the center, as most clearly shown in Fig. 4. Holes G are formed through the sides of the flukes close to their middle portions.

On one side of the shovel, at the middle thereof, I form a hub or lateral extension, H, and trunnions I are provided whereby to journal the shovel in the arms E". On the outer end of the hub H, I form teeth or projections H, corresponding in number to the flukes G, and

arranged alternately therewith, so that one tooth H will be arranged on each side of the base of each of the flukes. Depressions or receptacles H are formed in the hub in line between the teeth H, and so arranged as to deliver grain through the openings G into the fiukes.

The central portion of one side of the shovel may be removed, leaving a circular opening, which may be closed by acap or hub, N, over,- lapping the sides of the opening, and having an inwardly-projecting rim or centrally-raised portion, N, fitting within the opening and forming a bearing for the shovel to turn about. A recess, a, formed in the outerside, receives the outer end of one of the arms E, which is seated therein, and held in place by a bolt, which, passing through the opposite sides of the shovel and the end of the other arm, forms the trunnion for the opposite side of the shovel. The inner sideis provided with vertical flanges n, which register with the bore of the flukes or shovel-arms and give proper direction to the grain. An offset, N formed on one side near the upper edge of the cap, is hollowed out, making a receptacle or compartment, n. An opening, 16', leading from the bottom of the compartment, and extending through the cap, communicates with the space between the flanges. The tube J communicates with the spout O at its upper end, and its lower end extends into the receptacle H .or compartment n. The upper end, as shown in Fig. 1, is extended into the sleeve D, and is slotted, as shown in Fig. 7, to receive the point of the spout O. A roller, J is journaled in said tube in position to be engaged by the teeth I-lin the operation of the device, as will be presently described. The tube J is provided on one side with an extension, K, which projects below the open end of the tube, and is provided with a slot, K, which is placed in the trunnion I. This construction serves as a guide support for the lower end of the tube. It is obvious that the tube may be supported in various ways; but I prefer the construction above described, because of its simplicity and easy operation.-

In operation, when the parts are in the position shown in Figs. 1 and 10, the shovel is held from revolving so long as the fluke in the ground meets no unusual obstruction. When itstrikes such obstruction, the fluke, bearing against spring F or stops F, will depress and pass the spring or force apart the arms E and takethe place in the ground of the preceding fluke. The following one engages the spring F or stops F, as will be understood. vDuring this operation the connecting-tubeis elevated by means of the tooth H in rear of it, and is seated in the next following depression H as will be most readily understood from Fig. 5, in which the motions are indicated in dotted lines. The upper end of the tube, being provided with elongated slot J, permits the vertical movements thereof without interfering with the action of the spout 0.

While I prefer the construction before described, it will be understood that when so desired the sleeve D and spout 0 could be dispensed with and the spout J run directly into the grain-box, as shown in Fig. 8; or only the sleeve may be dispensed with and the spout C have its lower end communicate with the upper end of the tube, as shown in Fig. 10.

In practice I prefer to connect the shovel and tube by means of parts K, having slot K placed on the trunnion I or flanged hub.- plate N. However,where so desired, the con: struction shown in Fig. 9 maybe employed. In this figure the teeth H are dispensed with,

and the depressions H are formed with bev eled sides. The tube J has a band or collar, L,

which fits around the hub H. Within the tube I arrange a short tube, L, the lower endof which fits into the receptacle. H, and is beveled on its opposite sides corresponding to the receptacles H This part L is movable vertically in the tube J, and forms the lower-end thereof. The operation in this case would involve the-vertical movement of only the lower end, L, of the tube, instead of the whole tube, as in the other construction. This adjustment woud be affected by the revolution of the shovel, the beveled sides or receptacles H bearing against and elevating the part L.

This construction, it will be appreciated, involves no departure from the spirit of my invention, but only modifications of form of which may be made.

The conveyer or tube J maybe open on one side, preferably the upper side, to permit the attendant walking in the rear to observe the seed in its passagefrom the hopper to the shovel. The bore or passage j is wider near the upper end and narrower near the lower end, as most clearly shown in Fig. 15, to check the momentum of the grain and being dislodged by the jarring and up-and-down movement of the shovel. The lower end is pivotally connected with the offset N of the capplate N. l In order to spread the arms at any desire turn, to permit the fluke of the shovel in the ground to turn up out of the way, a link, 0, pivotal] y connected to one arm, extends transverselybeyond the other arm, and is provided with a roller, 0, for hearing on the inner side of the opposite arm when the link is turned about its pivotal connection by means of a rod, I, which extends within convenient reach of the attendant. The link is of ordinary construction, and the inner end is pivotally held within the clip 0. The roller is journaled between the arms of the link at such distance from the pivotal end that when the link is turned about said pivot the roller will contact with the opposite arm and force them the arms are sufficiently elastic, the bolt M and j springs m may be dispensed with. i

From the foregoing description and the accompanying drawings the operation of the device can be readily understood. However, it may be well to note that the grain is discharged from the hopper into the tube leading to the shovel in any well-known manner, the flukes of the shovel serving simply as a continuation ofthe conductor from the hopper to the ground.

As the mechanism for discharging the grain from the hopper is well known, and the same forms no part of the present invention, it is not shown.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a seeder, the combination, with a rotary shovel held normal from rotating, provided with hollow arms or flukes and having a series of openings near its center or axis, of the connecting-tube having its upper end connected with and receiving grain from the grainbox, and its lower end arranged to deliver the grain into the axial openings of the rotary shovel, substantially as and for the purposes set forth.

2.
